Physically based parametrs

it does, actually it works better than bump maps

[madcoo]

I'll try again, but last time I tried I only got small vertical stripes in my model...


Maybe because I used Bump at the same time????


Thanks Kubo, I'll keep you informed!

Normal map overrides a bump map

[madcoo]

Yep that's what I thought too...
I'll try again Normal mapping tonight...

[madcoo]

I tried again, but here's all I get...
I added my computer's specs in my signature if it can help...

I used a B/W image + Floatimage setting for the normal map - just the same one as I used for making bumps.

I'm using Octane v2.2b

Hi madcoo, normal maps looks different and you need image setting for it.

Cheers mib

Yes, normalmap is a RGB image, not grayscale like a bumpmap.
You will have to create it with specialized software - for example, I use the normalmap plugin for Gimp

Here's a nice & simple utility that another user posted somewhere on this forums:

Hey that's great!
I thought Octane supported b/w images for normal displacement (like other rendering softwares).
I'll have to look at your link on how to make a normal map.

Many many many thanks for your help!

[kubo]

that's why it wasn't working for you, a normal map has x,y and z vectors, each represented by a color RGB, a bump map just has a z vector black or white to represent depth, so to use a normal map you need a different type of map and you have to use it with a textureimage node not a float one. Here is a little freebie plugin from nvidia to do normals out of b&w depth maps in photoshop http://developer.nvidia.com/object/phot ... ugins.html.
Have fun and enjoy
edit: hehehe, matej you beat me for seconds, lol, anyway madcoo what you are talking about is displacement, this is bump, bump is a fake illusion to represent depth, displacement is the use of a depth map to create a real mesh with much more complexity, bump is faster but displacement looks better on close ups. Octane can't do displacement for now and as been debated before is not going to be an easy task to create displacement in gpu if ever, but..... (in Radiance we trust ) .

I just had a look at your links guys, this is purely AWESOME !!!
Many thanks (again) !!!
